Insects can feel pain??????

---

                                                              Pain is defined as “the unwanted emotions and experiences occurring in the body and mind”.  The pain is perceived differently by different organisms. As the level of pain perception in animals is not known, a research was conducted on it. In this research, similar to the reaction in humans to pain, the effects of pain on other organisms were studied. For example, when a dog is pricked with a needle it either runs or reacts in a different way.

Can you believe that insects cannot perceive pain? But it has been proved so! Only nociceptors have the ability send pain signals to the brain. But it has been found that these nociceptors are absent in insects which means most of the insects and animals are unable to perceive pain.

So it has been proved that some of the insects and animals which harm us, will not feel pain whatever we do to them. What do you think about this? Post your comments here.
